BLAST-FU'RNAC E.

SPECIFICATION forming part of Letters Patent No. 594,577, dated November30, 1897.

` Application led .Tnly 28, 1896. Serial N0. 600,764, (No model.)

To a/ZZ whom t may concern,.-

Beit known that I, MAXIMILIAN M. SUPPEs, of Lorain ,county of Lorain,State of Ohio, have invented certain new and useful Improvements inBlast-Furnaces, of which the following specification is a true and exactdescription, due reference'being had to the accompanying drawings.

My invention relates to certain improvements in blast-furnaces, andespecially relates to the charging of the furnace.

As furnaces have been heretofore operated difficulty has been met inproperly distributcharging-car hereinafter described. Fig. 3,

represents a side View of the charging-car. Fig. 4 shows a horizontalsection through the car, and Fig. 5 is a vertical section ofthe same.Fig. 6 is the same section of the car, but in the position to dischargethe load.

In a blast-furnace and the charging devices embodied in my inventionthere are preferably the following features: An elevator or skip-car forthe purpose of elevating the several elements of the charge from thestockyard to a point above the top of the furnace, where the charge istransferred to a chargingcar. This charging-car travels upon a trackpassing directly over the bell of the furnace, and when it reaches thispoint the load is discharged into the bell, from whence it is droppedinto the furnace. These being the general features, I will now describemy invention in detail.

Referring to Fig. 1, 1 is the furnace, the

top of which is closed by means of the bell 2. v

At a suitable point is the elevator or inclined railway 3, upon which isthe skip-car 4:, adapted to elevate the material from the stockyard.This skip may be operated by any means, as the rope 5, and it isarranged to automatically deliver its load into the charging-car 6. Thischarging-car travels upon the track 7, Which passes from thedeliverypoint. of the skip directly across the top of the furnace, sothat when the charging-car is loaded from the skip it may be brought toa point directly over the center of the furnace, as is shown in thedotted line in Fig. 1. When it reaches this point, the load is droppedupon the bell 2 of the furnace.

The charging-car is constructed in the following novel manner: The frameS in Figs. 3 to G lis supported upon the wheels 9 and carries thecylindrical iiXed top shell 10. Be-

neath this shell is supported the conical bot- .are the rods 14,connected to the bail 15. At

a point to engage this bail when the car is central over the furnace isany suitable lifting device, as the hook 16,' operated by suitablepower. (Not shown.)

When the car is in a suitable position to be emptied, it is necessarythat the bail be upright in order to engage the hook 16, and when it isreceiving the charge from the skip it should preferably be lying downout of the way. I providefor this in the following manner: Upon one endof the bail is the eXtension 17, projecting below the point ofsuspensionA and then extending' horizontally, as shown.

While the ear is to be under the skip the bail is down, but at the pointof travel toward the furnace Where it is desired to raise it I place inits path bar 18, having its end inclined, as at 19. When in the courseof travel of the car the arm 17 meets the incline, the bail is raisedand maintained upright as it moves toward hook 16. It Will be understoodIOO that while I have thus described the bail as movable it may also befixed and remain at all times upright.

The bell 2 is operated by suitable means, as

the hydraulic cylinder 2O and counterweight 2l, acting through levers22, yokes 23, and Suspenders 24. This construction is necessary in orderthat the charging-car may pass directly over the bell.

The operation of the several parts is as follows: The charging-car6,which may be moved by any suitable power, is brought under thedischarging position of the skip 4, and the several ingredients of thecharge are emptied from the skip into it. It is then moved along thetrack 7, the bail 15, which was in the first place down, rising as itengages the bar 1S until the car is directly over the bell 2. The hookI6 now engages the bail 15, and by means of it the shell 13 is lifted soas to form an oritice around the bottom of it. charge to flow out intothe mouth of the furnace, from whence from lowering bell it is droppedinto the furnace. The shell 13 is I(hen lowered and the car moved backfor another load. The distribution effected by the use of the conicalbottom is verysuperior, the charge falling upon the bell very evenlydistributed. This is a valuable feature, as even charging greatlyincreases the evenness of the output.

Having thus described my invention, what This allows thc I claim, anddesire to protect by Letters Patent, is-

l. A charging-car for blast-furnaces, comprising a frame supporting ashell and a bottom member a distance below the shell whereby there is anopening between the bottom and the shell and a vertically-movable shelladapted to close the opening and open it for the discharge of thecharge.

2. In a charging-car for blast-furnaces, a shell, a bottom, an annularorifice between the two and a vertically-movable shell adapted to closethe orifice and open it for the emptying of the charge.

3. In combination with a charging-car ofthe class described, a bail onthe operating member upon said car, a fixed stop adjacent to the trackupon which the car runs and adapted to engage the bail and set it in theproper position.

In testimony whereof I have affixed my signature in presence of twowitnesses.
